TECHNICAL FIELD

Embodiments of the present disclosure relate to solutions for remote provisioning of software modules which are configured to be stored in a memory of an integrated circuit card and enabled for operation, in particular a user profile or a bundle to be enabled in secure platform, hosted in a host device configured to communicate with a remote provisioning server, in particular a SM-DP+, to download, enable or disable such module by a remote provisioning procedure. Embodiments of the present disclosure relate in particular to integrated circuit such as smart cards, SIM, eSIM, eUICC (Universal Integrated Circuit Card), cards according the SSP (Smartcard Secure Platform) ETSI standard, M2M cards, and can be used for instance in the automotive field. The techniques here described may use for instance NFC techniques (Near Field Contact) and UWB (Ultra wide Band).

BACKGROUND

Due to new requirements of miniaturization and robustness, the industry has developed an evolution of the traditional UICC (Universal Integrated Circuit Card) cards, a smart card integrated in the communication device which is called “embedded UICC”. This evolution envisages that the UICC is soldered (or in any case made hardly accessible) in the hosting device that can be a mobile phone, a modem, a board inserted in a device, etc.

Soldering presents distinct advantages such as the possibility of reducing the size of the UICC device and hence of the modem, the improvement of the robustness of the contacts (soldered contacts are typically more reliable than interfaces between replaceable components), the increased antitheft protection.

On the other hand, soldering a UICC (or making it hardly accessible) introduces new requirements and issues that need to be addressed, such as: as the UICC is not replaceable, means should be available to allow the operator change; specific operations (such as device repairing), that today are typically performed after the UICC removal, require a way to disable the SIM card.

To address the above requirements, the industry has defined a new technological standard called “embedded UICC” or “Remote SIM provisioning”.

The basic concepts of the new technological standard are the following: one entity is defined to allow the download/enable/delete of profiles (for instance the Issuer Secure Domain Root ISD-R, see for instance “Remote Provisioning Architecture for Embedded UICC, Technical Specification, Version 1.0, 17 Dec. 2013”) the UICC may contain several mobile network operator subscriptions; each operator subscription is represented by a “profile”; every profile may be seen as a container; the container is managed by a security domain (for instance the Issuer Secure Domain Profile ISD-P)

In the eUICC (embedded UICC) card it is known to provide generation of profiles, in particular personalized profile package data.

A Profile is a combination of a file structure, data and applications which are stored in an eUICC. A Profile Package is a Personalized Profile using an interoperable description format which is transmitted to an eUICC in order to load and install a Profile.

For instance the consortium TCA (Trusted Connectivity Alliance) defines an interoperable format to represent a Profile Package as defined for instance in the TCA reference document “eUICC Profile Package: Interoperable Format Technical Specification”, available at the URL https://trustedconnectivityalliance.org/technology-library-sim-specifications/(Profile-interoperability-technical-specification_V1-0.pdf, see download section at referred link) and subsequent versions. Such interoperable format represents the structure of data to be built by the profile generating node, e.g. Profile Creator and to be loaded in the eUICC card in order for the eUICC to be personalized according to the content of the Profile Package. The Profile Creator is an entity in charge of creating the Profile Package based on the MNO (Mobile Network Operator) requirements.

Two families of embedded UICCs are currently defined: the eUICC Industrial cards; the eUICC Consumer cards; The eUICC Industrial cards are directed to application in automotive/M2M devices managed by a Service provider. Such devices are typically unattended, i.e. without the interaction of an End User. Thus the operation regarding the managing of software and profiles, e.g. Load/ Enabled/Disable/Delete are issued by a remote server, representing the service provider, since the device performs these operations unattended.

On the other hand, the eUICC Consumer cards are directed to mobile phones, smartwatches, and similar device which are typically attended. Therefore, operations for managing software and profiles are issued by the local device, representing the user intent. The device performs these operations attended, i.e. with the interaction of an End User.

In FIG. 1 it is shown a schematic representation of a system for managing profiles in industrial eUICC cards 10, which includes a data preparation server 11, e.g. a SM-DP server, responsible for the creation, generation, management and the protection of resulting profiles at the input/request of the operator. Such data preparation server 11 for instance may include a database of profiles and, additionally other modules like an OTA RFM (Over The Air Remote File Management) engine and a Keys Manager. The data preparation server 13 provides, for instance through an OTA (Over The Air) channel, profiles P, in particular personalized profiles, to a Secure Routing server 21, e.g. a SM-SR server, which is configured to secure routing of profiles and usually sends a profile download enabling command to the eUICC card 16, which is embedded in a local equipment 14 (as visible in FIG. 2), i.e. a smart card integrated in a local communication device, thus enabling download and storing of the profile P in the eUICC card 16. The system 10 includes also a Mobile Network (MNO) operator 22, which can issue for instance a profile ordering command to the data preparation server 13. In FIG. 1 are also indicated a Certificate Issuer 23, which issues Certificates for remote SIM provisioning entities and acts as a trusted third party for the purpose of authenticating the entities within the system, and an eUICC Manufacturer (EUM) 24 which is responsible for the initial cryptographic configuration and security architecture of the eUICC 16 and is the provider of eUICC products. These system components are not here described in further detail. A description of the operation of the system 10 can be found at https://www.gsma.com/iot/wp-content/uploads/2014/01/1.-GSMA-Embedded-SIM-Remote-Provisioning-Architecture-Version-1.1.pdf and subsequent versions.

Thus, in the system 10, the SM-DP (server 11, an OTA server) contains profiles and represents the MNO. The SM-SR (server 21, also an OTA server) executes commands [load/enable . . . ] in batches over the device installation basis, e.g. downloading profiles on all the cards on the field.

In FIG. 2 it is shown a schematic representation of a system for managing profiles in consumer eUICC cards 10′, where the data preparation server 13, which is specifically a SM-DP+, i.e. Subscription Manager Data Preparation—enhanced compared to the SM-DP in SGP.02, interacts directly with the local equipment 14, e.g. a mobile telephone or smartphone, and specifically with a software profile management module configured to store profiles in the eUICC 16 and perform operations on said profiles P stored in the eUICC 16, such module being specifically a LPA (Local Profile Assistant) software module 15.

The LPA module 15 is a software running in the local equipment 14 and provides LPA services, such as Profile download or Profile management, to the eUICC 16. The LPA consists of two parts—the LPD (Local Profile Download) 14 a and the LUI (Local User Interface) 14 b. The LPD 14 a plays a proxy role for the efficient download of a Bound Profile Package between SM-DP+ 13 and eUICC 16, while the LUI interface 14 b allows for local profile management on the device by an end user 20. The end user 20 can interact with the local equipment 14 through a user interface or with the MNO 22 through an operator interface. A Local Discovery Service (LDS) 14 c is also shown as included in the LPA module 15. The system 10′ includes also a Subscription Manager-Discovery Server (SM-DS) 25 to provide mechanisms that allow an SM-DP+, like the server 13, to inform the Local Discovery Service 14 c within any device that an SM-DP+ like server 13 wishes to communicate with it. A description of the operation of system 10′ can be found at https://www.gsma.com/aboutus/wp-content/uploads/2015/01/FS.08_SAS-SM_Standard_v_(3.0).pdf.

Thus in the consumer architecture of the system 10′ the SM-DP+ server (an OTA server) contains profiles and represents the MNO. The LPA (an application on the local equipment, e.g. the phone) executes commands [load, enable . . . ] on the user equipment phone. The user changes operator, for instance, by means of the GUI (Graphical User Interface) of the LPA.

The techniques here taken in consideration are those where MNOs (Mobile Network Operators) do not accept peer to peer profile/bundle transfer.

A possible scenario in such circumstances is that of a user desiring to perform on operation such load, enable or disable a subscription.

This operation may encounter problems. If using an integrated circuit card such as M2M eSIM, this kind of card just relies on Remote Management, i.e. the load/enable/disable initiative is started by the MNO, not the user. If using a Consumer eSIM, within a screenless device (e.g. antenna, smart meter), no user interface is available, thus this cannot be done.

In the following description, numerous specific details are given to provide a thorough understanding of embodiments. The embodiments can be practiced without one or several specific details, or with other methods, components, materials, etc. In other instances, well-known structures, materials, or operations are not shown or described in detail to avoid obscuring aspects of the embodiments.

Thus, the appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification is not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

The headings provided herein are for convenience only and do not interpret the scope or meaning of the embodiments.

Figures parts, elements or components which have already been described with reference to FIG. 1 are denoted by the same references previously used in such Figures. The description of such previously described elements will not be repeated in the following in order not to overburden the present detailed description.

In brief, the solution described provides using a subscriber contactless communicating device, in particular a smartcard, for instance operating according to NFC or UWB, to trigger the provisioning or enabling or disabling of a software module in an integrated circuit card by means of a contactless transaction.

Following the contactless interaction, such as a card tap, between the contactless device and the device comprising the integrated circuit card, in particular by placing the contactless subscriber device within the communication range determined by a corresponding contactless interface in the host device, after a mutual authentication between the contactless device and the IC card in the host device, a subscriber identifier, i.e. identifying subscription to a certain profile or software bundle, stored in the subscriber contactless communicating device is sent to the IC card. The IC card checks the subscriber identifier against identifications stored in the card, performing one operation among downloading the software module, enabling the software module or disabling the software module in function of the result of said checking operation, i.e. the subscriber identifier is respectively not already stored, disabled or enabled.

In FIG. 3 is schematically described a system for remote provisioning configured to operate with the method of the solution here proposed.

The system 10″ corresponds to that shown in FIG. 2. However, a subscriber contactless device 31 is provided which is operable by the user 20, e.g. a NFC card which stores a subscriber identifier representing a subscription to the local equipment 14. Such local equipment 14 further includes a contactless interface 32, e.g. a NFC interface, including a NFC transceiver, in order to communicate with the subscriber contactless device 31 when such subscriber contactless device 31 is placed within the communication range determined by the corresponding contactless interface 32 in the host device, i.e. the local equipment 14. Near-Field-Communication (NFC) may refer to a set of communication protocols for communication between two electronic devices over a distance of 4 cm or less, for instance according to ECMA-340 and ISO/IEC 18092 standards. In variant embodiments, UWB technology may be used, with a UWB tag as the device storing the subscriber identity 31 and an UWB module. The UWB tag may operate as the contactless interface 32, e.g., inside a vehicle, allowing access to a local equipment 14 ,which may be the mobile communication system of the vehicle or another equipment using a M2M card.

In FIG. 4 it is shown a flow diagram illustrating operations of an embodiment of the method here described, indicated with the reference number 100.

The method includes in a step no performing a contactless interaction between the subscriber contactless device 31, e.g. a NFC card, and the local equipment 14, e.g., a smartphone or tablet, comprising the integrated circuit card 16, for instance an eSIM. This embodiment is performed by placing the contactless subscriber device within the communication range determined by a corresponding contactless interface, e.g., a NFC interface 32 associated to the local equipment 14.

Then, at 120, a mutual authentication is started between the subscriber contactless device 31 and the integrated circuit card 16 in the local equipment 14. The integrated circuit card 16 jointly with the local equipment 14 and the contactless interface 32 may be considered equivalent to a contactless reader, in particular a NFC reader, and mutual authentication protocol between contactless tag and reader may be performed. Authentication information to perform the mutual authentication may be stored also in the integrated circuit card 16, i.e., the subscriber contactless device 31 and integrated circuit card 16 may store and execute mutually cooperating encryption algorithm to perform such mutual authentication certificate based on, e.g., a digital signature, inSign, ETSI-MSS, or two (or multi) factors.

At 130, a subscriber identifier SID stored in the subscriber contactless communicating device 32 is sent to the integrated circuit card 16, asking the integrated circuit card 16 to perform a check operation on the subscriber identifier SID. The subscriber identifier SID is an identity code or number identifying a specific subscription, e.g. a specific profile P.

At 140, the integrated circuit card 16 checks the subscriber identifier SID by comparing it with other subscriber identities stored in the integrated circuit card 16. In particular, the subscriber identities stored in the integrated circuit card 16 correspond to profiles P and the card is able to detect whether they are absent, disabled or enabled.

The checking operation 140 selects one of the following as an output: downloading 200 the software module, e.g. the profile P, enabling 300 the software module and disabling 400 the software module. For example, the operation may detect that the software module, i.e. profile P, is respectively absent, already present disabled or already present enabled.

Each of operations 200, 300, 400 scenarios involves interaction with a remote provisioning server, in particular SM-DP+ server 13, as shown in FIG. 2, although in variant embodiments SM-SR similar to the one in FIG. 1 may be used.

Operations 110-140 and 200 are described in further detail with reference to the sequence diagram of FIG. 5, which represents actions T1 . . . T8 performed by some of the entities or nodes of the system 10″ schematically represented in Figure 3. Specifically transactions among the subscribed contactless device 31, the local equipment 14, the integrated circuit card 16, in this example an eSIM, the remote server 13, a SM-DP+, and a mobile communication network 40 are shown.

In a first transaction T1 the user 20 performs operation 110, i.e. taps the subscribed contactless device 31. As it is known tapping a NFC card means bringing the NFC circuit in close proximity, within the range allowed by the NFC technology for communication, with a corresponding NFC interface in the local equipment 14. In variant embodiments, where the subscriber device 11 is a device equipped with a UWB communicating module, the range allowed by the UWB is far greater, therefore the interaction is better defined as placing the subscriber device 11 within the communication range of the corresponding interface in the local equipment 14.

Then in transaction T2 a mutual authentication between the subscribed contactless device 31 and the eSIM card 16 is performed, in particular through the local equipment 14 and interface 32, performing operation 120. The subscriber contactless device 31 then sends T3 a message to eSIM card 16 asking to check subscriber identifier SID, which is performed as operation 140 in FIG. 4. In case the subscriber identifier SID does not match the ones the eSIM card 16 has on-board, i.e., the profile corresponding to the subscriber identifier SID received is absent, the eSIM card 16 replies in a transaction T4 with its card identifier, in particular eUICC Identifier, EID, to the local equipment 14. The local equipment 14 is configured to, upon receiving the eUICC Identifier EID from the card 16, to perform a transaction T5 sending a Profile Downloading Request to the server 13, SM-DP+, with SID identifier. The server 13 responds to the Profile Downloading Request preparing and sends in a transaction T6, an encrypted profile, specifically a Protected Profile Package, to the local equipment 14.

Then the profile P in a transaction T7 is loaded by the LPA in the integrated circuit card 16. The eSIM 16 in a transaction T7 enables the profile P and in a transaction T8 connects to the mobile network 40. This means that the local equipment 14 with the eSIM 16 can now operate, e.g., exchange phone calls and data, with the mobile network 40 according to the subscription defined in profile P.

Thus operation 200 substantially corresponds to transactions T4-T8 in FIG. 5.

Operations 110-140 and 300 are described in further detail with reference to the sequence diagram of FIG. 6, which represents actions T1 . . . T3, T14 . . . T17 performed by some of the entities or nodes of the system 10″ schematically represented in FIG. 3. In a first transaction T1 the user 20 performs operation 110, i.e. taps the subscribed contactless device 31. Then in transaction T2 a mutual authentication between the subscribed contactless device 31 and the eSIM card 16 is performed, in particular through the local equipment 14 and interface 32, performing operation 120. The subscribed contactless device 31 then sends T3 a message to eSIM card 16 asking to check subscriber identifier SID, which is performed as operation 140 in FIG. 4. In a first transaction T1 the user 20 performs operation 110, i.e. taps the subscribed contactless device 31. Then in transaction T2 a mutual authentication between the subscribed contactless device 31 and the eSIM card 16 is performed, in particular through the local equipment 14 and interface 32, performing operation 120. The subscribed contactless device 31 then sends T3 a message to eSIM card 16 asking to check subscriber identifier SID, which is performed as operation 140 in FIG. 4.

In case the subscriber identifier SID matches an identification the eSIM has already on-board, i.e. a profile P with the subscriber identifier SID is already present and it is enabled, the eSIM 16 issues a reply T14 comprising a corresponding information to the local equipment 14. The local equipment 14 in a transaction T17 communicates to the eSIM card 16 that the profile P is to be disabled and the eSIM card 16 disables the profile P.

Operations 110-140 and 400, are described in further detail with reference to the sequence diagram of FIG. 6, which represents actions T1 . . . T3, T24 . . . T27 performed by some of the entities or nodes of the system 10″ schematically represented in FIG. 3. In a first transaction T1 the user 20 performs operation 110, i.e. taps the subscribed contactless device 31. Then in transaction T2 a mutual authentication between the subscribed contactless device 31 and the eSIM card 16 is performed, in particular through the local equipment 14 and interface 32, performing operation 120. The subscribed contactless device 31 then sends T3 a message to eSIM card 16 asking to check subscriber identifier SID, which is performed as operation 140 in FIG. 4. In a first transaction T1 the user 20 performs operation 110, i.e. taps the subscribed contactless device 31. Then in transaction T2 a mutual authentication between the subscribed contactless device 31 and the eSIM card 16 is performed, in particular through the local equipment 14 and interface 32, performing operation 120. The subscribed contactless device 31 then sends T3 a message to eSIM card 16 asking to check subscriber identifier SID, which is performed as operation 140 in FIG. 4.

In case the subscriber identifier SID matches an identification in the eSIM 16 has onboard, i.e. a profile P with the subscriber identifier SID is already present and it is disabled, the eSIM 16 issues a reply T24 comprising a corresponding information to the local equipment 14. Then, the card 16 is asked by the local equipment in a transaction T27, similar to transaction T17, to enable the profile P. Upon such asking T27, the eSIM card 16 then performs the enabling of the profile P. Once the profile is enabled, registration operations on the network (e.g. on the SM-SR server) may follow.

The local equipment 14 communicates in transaction T27 that the profile P is enabled to the eSIM 16, i.e. the local equipment 14 with the eSIM 16 can operate, e.g. exchange phone calls and data, with the mobile network 40 according to the subscription defined in profile P.

The method described can be applied also to a software module which is a Secondary Secure Platform bundle, which has to be downloaded to a Secure Platform in a card and then enabled, or vice versa disabled if already present.

The operation 110, performing a contactless interaction between the subscriber contactless device 31, and the local equipment 14 associated to integrated circuit card 16, is performed by placing the contactless subscriber device 31 within the communication range determined by a corresponding contactless interface, e.g. NFC interface 32, associated to the local equipment 14, but it can be performed also using UWB for automotive, for instance when the NFC tap is not suitable. Since the presence of the subscriber identifier SID in the radio coverage area is not enough to guarantee the user intention, it requires a further step, such as a user interaction with a graphic interface menu, or other input means of the local equipment, in particular in the vehicle this example, equipped with a UWB interface and an integrated circuit card which stores a profile P or in which a profile P has to be downloaded.

Thus, the method proposed by using a contactless interface allows: profile management even if device is not equipped with a display and/or not portable and/or not reachable (UWB); profile management within a vehicle just accessing NFC antenna; for UWB, Profile management within a vehicle, without accessing soldered module or NFC antenna, for instance by means of an input means represent by a vehicle display.
